Product Information This Air Compressor Bundle can be installed on the 7350 thru 7750 and 7280 thru 7780

Self-Propelled Forage Harvesters to reduce time in cleaning and service of the machine.

This bundle is not compatible with any machines built prior to MY2012. It will also not fit

the 7250, 7180, 7950 and 7980 models. No bundle exists for these other machines.

The RC077001 Air Compressor Bundle is available from RCI ENGINEERING LLC with

the following specifications:

Rated Flow: 13.2 CFM @ 90 psi

Rated Pressure: 90-115 psi (unloader valve settings)

Reservoir: 10 Gallons

IMPORTANT: Machines equipped with IT4 Engines have the auxiliary drive installed

from the factory. Non-IT4 engines may or may not have the auxiliary drive gears installed

from the factory. File a DTAC case to confirm and to determine options for having John

Deere install the auxiliary drive gears as needed. Also, a software update from John Deere

is required for MY2012 machines for proper function. The air system is only enabled

when the machine is in Park. During installation, make sure all controllers are updated to

the latest software.

Estimated Install Time: 5 to 7 hours, depending on technician experience. This does not

include the time required to install the auxiliary drive gears or updating software.

Safe Operation of Machine

Operator Authorization

The machine owner must provide the operator of the machine this manual and ensure

that the operator reads and understands the contents. This must be performed before

the machine is put into operation.

Safety Alert Symbol

This safety alert symbol is used to alert the operator to the

potential for personal injury. Whenever this symbol is

noticed in this manual or on the machine, be alert to the

situation and read the message near the symbol. Always be

alert for the potential for personal injury.

General Safety Precautions / Accident Prevention

Before operation of the machine each time, check the entire machine for operational

safety.

1/ Read Operator's Manual completely before transporting unit.

2/ Do not use air system unless machine is in Park and all harvesting components have

stopped moving.

3/ Do not use the air system to clean the engine compartment unless the engine has been

turned off.

4/ Inspect safety valve regularly and replace or repair if defective.

6

Maintenance

Check for water in air tank every 100

hours of machine use. Drain as

necessary.

Replace the air tank per the

recommendation specified on the tank.

Repair Parts

General Comments

The following pages include information

regarding parts for the Air Compressor

Bundle. Right or left hand parts are

determined by sitting in the operator’s seat

facing forward. The abbreviation “A.R.” in

the “USED” column indicates “As

Required.” This is because a different

number of the specific component may be

needed for proper assembly depending on

the tolerance of the individual machine.

Replacement Hardware

All bolts, cap screws, washers and machine

screws are grade 8.8 and zinc plated unless

markings on the part indicate otherwise.

Flange bolts and flange nuts are metric

grade 8.8 and zinc plated unless markings on

the part indicate otherwise.

The use of improper hardware in any

location can result in the failure of the

component fastened with the hardware or

related structures, and can cause personal

injury, further damage to the product, or loss

of property.

Replacement Parts

Replacement parts may have occasional

differences to the parts being replaced. This

difference is typically providing the benefit

of a design change made after the release of

this publication.

Installation Instructions 1.0 Mount Compressor

1.1 Drain cooling system as needed.

Note: This is to install the coolant lines to the air compressor.

1.2 Remove access cover of auxiliary drive.

1.3 Assemble Air Compressor and adapter as shown in Figure 2.

Install Air Compressor and Gasket. Install two mounting cap screws and tighten to

specifications. Reuse mounting cap screws from cover plate.

Specification:

Air Compressor Mounting Cap Screw Torque 102 Nm (75 lb-ft)

Install mounting support block and hardware (Key 34 in Figure 2). Tighten properly.

1.4 Install oil supply line and fittings.

Secure oil lines as shown with P-Clamps and supplied hardware.

1.5 Install coolant lines to air compressor.

1.6 Fill cooling system.

Note: The Air Compressor on the 13.5L Engine, depending on vintage of engine, may

interfere with one of the tabs of the block of the engine as shown in Figure 1. Use a cut-

off wheel / grinder to remove half of the ear prior to compressor installation if interference

occurs. This compressor system and installation are common to John Deere 12.5/13.5 L

engines. See the “Remove and Install Air Compressor” section of the technical manual for

the 6135 Engine for any further details needed.
